Abstract: A gamma correction apparatus for a display device, includes: a measurer configured to measure an optical characteristic of a display panel; and a gamma data generator configured to generate measurement gamma data for at least one measurement gray level pre-determined from among a plurality of gray levels, based on the optical characteristic received from the measurer, generate prediction gamma data for at least one prediction gray level other than the at least one measurement gray level from among the plurality of gray levels by using an equation defining a relationship between a gray level and an optical characteristic, and generate gray level-wise gamma data, based on the measurement gamma data and the prediction gamma data.

Abstract: A touch panel includes: a substrate; a plurality of sensor electrodes disposed on the substrate; and a dummy pattern disposed on the substrate among the plurality of sensor electrodes. Each of the sensor electrode includes a plurality of first mesh patterns extending in a first direction and a plurality of second mesh patterns connecting adjacent ones of the plurality of first mesh patterns in a second direction, and the dummy pattern includes a plurality of third mesh patterns extending in the first direction and one or more disconnected portions on an extension path of the plurality of third mesh patterns.
